  • Ethylene - Wikipedia
    Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C2H4 or H2C=CH2 It is a colourless, flammable gas with a faint "sweet and musky " odour when pure [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds) Ethylene is widely used in the chemical industry, and its worldwide production (over 225 million tonnes in 2022) [8] exceeds that of any other
  • Ethylene | Structure, Sources, Production, Uses, Facts | Britannica
    Ethylene, the simplest of the organic compounds known as alkenes, which contain carbon-carbon double bonds Natural sources of ethylene include both natural gas and petroleum; it is also a hormone in plants, in which it inhibits growth and promotes leaf fall, and in fruits, in which it promotes ripening
  • What Is the Ethylene Molecule and How Is It Used?
    Ethylene is one of the simplest organic molecules in existence, a small hydrocarbon that consists of just two carbon atoms and four hydrogen atoms This molecule is a fundamental building block of chemistry, and its presence is ubiquitous, found everywhere from the cells of a ripening fruit to the structure of modern plastics Its simplicity belies its profound influence, acting as a gaseous
